Operating system kernel

Redox is a POSIX-compliant, microkernel-based operating system written entirely in Rust. By utilizing a memory-safe language for the kernel and all system components, the project eliminates common vulnerabilities such as buffer overflows and use-after-free errors. Its architecture relies on a minimal kernel that manages only essential hardware and process isolation, delegating all other system services to unprivileged user-space processes. The system distinguishes itself through a modular design where hardware drivers and system services run as independent user-space daemons, allowing them to

SerenityOS is a complete, self-hosted desktop operating system built from the kernel up. It features a monolithic kernel architecture that manages system services, hardware drivers, and networking within a single address space. The system provides a full computing environment, including a proprietary windowing system and a suite of native desktop applications, all while maintaining a POSIX-compliant interface for standard system programming. The project is distinguished by its integrated development workflow, which relies on a cross-compilation build pipeline to generate system images from ho

ReactOS is an open-source operating system designed to be binary compatible with Windows applications and drivers. It consists of a low-level system kernel that manages hardware resources and a binary compatibility layer that enables the execution of software designed for the Windows binary interface. The project implements a cross-platform build system and toolchain for compiling and deploying bootable operating system images across different hardware architectures. This includes the use of cross-compilation toolchains and a hardware-abstraction layer to support various processor and motherb

This repository contains the complete source code for a Unix-like operating system, including the monolithic kernel and base system utilities. It provides a BSD-derived system core and a full build toolchain required to compile a functional operating system for servers, desktops, or embedded devices. The system features a Linux binary compatibility layer that enables the execution and emulation of Linux binaries on a non-Linux platform. It also includes a modular kernel configuration process to tailor hardware support and system features during compilation. The project covers broad system ca

Rocky is an open-source enterprise operating system designed for server and cloud infrastructure. It is a community-maintained Linux server distribution that provides a platform focused on stability and security. The project is fundamentally a Red Hat Enterprise Linux compatible operating system, maintaining bug-for-bug binary compatibility to ensure identical software behavior. This allows it to serve as an enterprise-grade platform without proprietary licensing. The distribution covers a broad range of system administration capabilities, including package management via modular repository

OpenWrt is a modular Linux distribution designed for resource-constrained networking hardware. It functions as a comprehensive network routing platform, providing a complete build environment that allows users to generate custom firmware images for a wide variety of embedded processor architectures. By utilizing a standardized cross-compilation toolchain and a package-based ecosystem, it enables the creation of tailored operating systems for specific hardware deployments. The project distinguishes itself through a hardware abstraction layer that normalizes interactions across diverse chipsets

OpenMediaVault is a Debian-based network attached storage (NAS) operating system that turns a computer into a dedicated storage appliance, managed entirely through a browser-based control panel. It provides a unified configuration interface for managing file sharing protocols, RAID arrays, user permissions, and network services, with extensibility through a modular plugin system that adds new capabilities without modifying the core installation. The platform supports setup and management of multiple RAID levels for data redundancy or performance, and exposes file storage over protocols includ

Open-smartwatch-os is an operating system designed for resource-constrained wearable devices. It provides a development and testing environment that allows developers to build, validate, and debug firmware for smartwatches within a simulated desktop environment before deploying to physical hardware. The project distinguishes itself through a comprehensive suite of tools for hardware emulation and remote diagnostics. By utilizing a hardware abstraction layer and modular driver architecture, it decouples core system logic from specific physical components. This enables developers to run the ope

ZealOS is a 64-bit operating system designed for bare-metal deployment and custom kernel development. It provides a self-contained environment that operates within a single-address-space memory model, where all software executes in a ring-zero privilege level to eliminate context switching and facilitate direct hardware interaction. The system distinguishes itself through a monolithic architecture that integrates just-in-time compilation, allowing source code to be translated into machine instructions during runtime. It bypasses traditional abstraction layers by utilizing direct hardware memo

Cinnamon is a desktop environment interface for Linux operating systems. It provides a visual layout and user interface for managing windows and applications, focusing on desktop workflow management. The project enables Linux GUI customization, allowing the look and feel of the environment to be modified. It includes a window management system to handle the placement and behavior of application windows within the workspace. The environment utilizes a JavaScript-based shell and a modular applet architecture for extensibility, while using CSS for component styling. The interface is built with

This project is a configuration suite for the Hyprland Wayland compositor, providing a set of automated scripts and files to deploy a consistent desktop environment across Linux distributions. It functions as an automation tool that synchronizes system settings, software packages, and interface themes to ensure a uniform workspace state. The environment distinguishes itself through deep integration with language models, allowing users to access local or cloud-based AI assistants directly from the desktop interface for tasks such as text translation and content generation. Visual consistency i

Qtile is a programmable tiling window manager and compositor written and configured in Python. It organizes application windows into non-overlapping tiles or floating modes to maximize screen real estate and supports both X11 and Wayland display server protocols. The environment is defined by executing Python scripts, allowing the programmatic customization of keybindings, visual styles, and system behaviors. This approach enables a personalized workspace where the entire user interface and layout logic are managed through a script-based configuration. The project covers broad capability are
